Abstract (en)
[origin: CA3067733A1] The invention relates to a method (100) for separating a starting mixture which largely contains hydrogen, methane, and hydrocarbons with two or two and more carbon atoms, wherein at least one part of the starting mixture is cooled, thereby forming one or more condensates, using one or more heat exchangers (101, 103, 105, 107), and at least one part of the condensate(s) undergoes a rectification process, thereby forming a gaseous methane-enriched fraction. The gaseous methane-enriched fraction is at least partly used to form a first fluid flow which is condensed to a liquefaction pressure level of 35 to 45 bar in the composition which is unchanged relative to the gaseous methane-enriched fraction and is at least partly liquefied by means of a cooling process, and the first fluid flow or a second fluid flow which is formed using the first fluid flow is expanded to a discharge pressure level and is heated in the heat exchanger or at least one of the heat exchangers (101, 103, 105, 107). The invention likewise relates to a corresponding system.
